I like Fossil ( fossil-scm.org ). Sync public repos to chiselapp.com, keep private ones on my ssd or sync to my vps shell account. Resistant to US cloud takedown, e.g. if you’re running logistics to defend Greenland 😉

Reputable military never use tear gas, etc. It’s a chemical weapon, and hard to distinguish from lethal ones. So it would invite a Sarin/GB/VX response from enemy, which they don’t want.

I write a tech blog on Gemini ( https://geminiprotocol.net/) , and read other people’s blogs from the Antenna aggregator on that network . IRC is still quite active for some topics, again on the tech theme libera.chat is the place to go now.

Same answer as last time this was asked, I am very happy with Posteo.
